ASoC: uniphier: change status to orphan

Since I'm leaving from Socionext, I'll unable to access specification
documents of this hardware (these are not public). So change the
state to orphan until someone will maintain this driver.

ASoC: rsnd: fixup not to call clk_get/set under non-atomic

Clocking operations clk_get/set_rate, are non-atomic,
they shouldn't be called in soc_pcm_trigger() which is atomic.

Following issue was found due to execution of clk_get_rate() causes
sleep in soc_pcm_trigger(), which shouldn't be blocked.

We can reproduce this issue by following
> enable CONFIG_DEBUG_ATOMIC_SLEEP=y
> compile, and boot
> mount -t debugfs none /sys/kernel/debug
> while true; do cat /sys/kernel/debug/clk/clk_summary > /dev/null; done &
> while true; do aplay xxx; done

This patch adds support to .prepare callback, and moves non-atomic
clocking operations to it. As .prepare is non-atomic, it is always
called before trigger_start/trigger_stop.

Commit a655de808cbde ("ASoC: core: Allow topology to override

be come dependent on the substream private_data being set with
a pointer to the snd_soc_pcm_runtime. Currently, CODEC to CODEC
links don't set this, which causes a NULL pointer dereference:

[<4069de54>] (soc_dai_hw_params) from

Since the ASoC core in general assumes that the substream
private_data will be set to a pointer to the snd_soc_pcm_runtime,
update the CODEC to CODEC links to respect this.

On some platforms it has been noted that a pop noise can be
witnessed when capturing audio, mainly for first time after a
headset jack has been inserted. This is due to a DC offset in the
Mic PGA and so to avoid this delays are required when powering
up the capture path.

This commit rectifies the problem by adding delays post Mic PGA and
post Mixin PGA. The post Mic PGA delay is determined based on
Mic Bias voltage, and is only applied the first time after a
headset jack is inserted.

ASoC: compress: make BE and FE order inline with dpcm

For some reason order of startup/hw_params/prepare are reversed
in dynamic compress usecase when compared to dpcm usecase. This is
a issue with platforms like QCOM where it expects the BE to be
initialized before FE.

Interestingly the compress trigger callback order is inline with dpcm.

Am not 100% sure why the compress audio case has been reversed.
This patch is making the order inline with dpcm.

If the reverse ordering is just co-incendental then this change
makes sense and will avoid inventing some new mechanism to cope
with ordering.

ASoC: wcd9335: add support to wcd9335 codec

Qualcomm WCD9335 Codec is a standalone Hi-Fi audio codec IC,
It supports both I2S/I2C and SLIMbus audio interfaces.
On slimbus interface it supports two data lanes; 16 Tx ports
and 8 Rx ports. It has Seven DACs and nine dedicated interpolators,
Seven (six audio ADCs, and one VBAT ADC), Multibutton headset
control (MBHC), Active noise cancellation and Sidetone paths
and processing.

This patchset adds very basic support for playback and capture
via the 9 interpolators and ADC respectively.

ASoC: sirf: Fix potential NULL pointer dereference

There is a potential execution path in which function
platform_get_resource() returns NULL. If this happens,
we will end up having a NULL pointer dereference.

Fix this by replacing devm_ioremap with devm_ioremap_resource,
which has the NULL check and the memory region request.

This code was detected with the help of Coccinelle.

ASoC: dmaengine: Use standard pcm_format_to_bits() macro

The conversion from PCM format type to bits needs an explicit cast,
and it'll be uglier.  Since we have a standard macro for that, let's
use it instead.

This patch fixes the sparse warning:

Fix them in the following two ways:

- The open code with snd_mask_set() and params->masks reference is
  replaced with params_set_format()

- The rest codes with snd_mask_set(fmt, SNDRV_PCM_FORMAT_XXX) are
